Æ20

Klazomenai, one of the twelve cities of the Ionian League, had a complicated relationship with autonomy — Persian-controlled for much of the classical period, it was Alexander's conquest that restored meaningful civic independence. Bronze coinage of this type belongs to the long Hellenistic phase of that renewed autonomy, during which the city operated as a nominally free polis under successive Seleucid and later Pergamene influence before the region passed definitively to Rome after the bequest of Attalos III in 133 BC.

The SNG Copenhagen and Munich concordances place this type firmly within the civic bronze series, struck over a production span long enough that die wear and fabric variation between specimens can be considerable.
